Patent GB-1093375-A (GB)
Title: Surface coating compositions comprising isocyanate reaction products
Inventor: MARKLOW RAYMOND JOSEPH
IPC: C08G18/64
Filed: 1964-11-06
Abstract: Coating compositions consist of a solution in an inert organic solvent of a compound having terminal -NCO groups, prepared by reacting pitch with a polyisocyanate.  The pitch may be mixed before reaction with another compound containing isocyanate-reactive groups, or the pitch-isocyanate product may be modified by reaction with another isocyanate-reactive compound. Suitable additional compounds are hydroxyl-containing polyethers or polyesters, castor oil, polyols, polyamines, and compounds containing epoxy groups, e.g. a resin from epichlorhydrin and diphenylolpropane.  Reaction is preferably at 50-200 DEG  C.  The reaction mixture must contain an excess of NCO groups to give a product containing two or more such groups/mol.  Any conventional di- or tri-isocyanates may be used.  If volatile ones are used, the reaction product should be freed from excess.  The solvent preferably boils above 75 DEG  C.  Suitable solvents are ethyl, butyl or ethoxylethyl acetate, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone.  The coatings store well in absence of moisture, and set with atmospheric humidity. Pigments, fillers, flame-proofing agents, surface-active materials, catalysts and antioxidants may be present.  In examples:  (1) pitch, a diphenylmethane - 4,41 - diisocyanate composition, and 2 - methyl - 2 - methoxypentan - 4 - one are heated together at 80-90 DEG  C.; (2) castor oil, or a polyester or polyether and the solvent are first heated with the polyisocyanate and the pitch then added and heating continued.  Other examples are similar.

Title: Improvements in or relating to flying bodies
IPC: B64C23/00
Filed: 1963-11-20
Abstract: 1,071,026. Propelling aircraft. H. WERNER VON ENGEL. Nov. 20, 1963 [Dec. 11, 1962], No. 45810/63. Heading B7G. [Also in Division F3] An electrically conducting flying body has only rounded edges and is cross shaped in plan, the body being electrostatically charged when subject to natural fields in the atmosphere. The flying body incorporates propulsion units (15, 16) at each end of the fuselage (11) and wing (12) structures, the units being pivotally mounted about axes S 1 -S 1  to S 4 -S 4 . The propulsion units (15, 16) consist of rocket or jet-propulsion motors with heavy metal colloids added to the fuel which is incompletely burnt and ions are produced by contact with the nozzle walls so that positively charged ions are emitted in the gas stream (6) into the atmosphere to create artificial space charges while the negatively charged nozzle transmits its charge over the entire flying body (5). The space charges which may be entirely artificial or may be naturally formed (e.g. in clouds or the ionosphere) and intensified by the generator units. Intermittent operation of the generators is disclosed. Other types of generator include liquid fuel rockets, internal combustion engines, metals having a high electron emissivity when heated such as thorium, tungsten, barium, rhenium or their alloys, radioactive isotopes such as strontium 90 or volatile oils having a complex molecular structure which decomposes when sprayed into the atmosphere. Remote control of the generators may be made by use of lasers or radio waves.

Title: Method of forming a vesicular image
IPC: G03C5/60

Abstract: 1,031,823. Photographic vesicular materials. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 6, 1962 [Dec. 7, 1961], No. 46149/62. Heading G1C. Vesicular images are produced by exposing internally a film containing two vesicular materials in a polymeric binder so that one material produces a gas on exposure, relaxing the material to form invisible baubles (eg a maximum diameter of 0. 5 microns) and then image-wise expiring the film so that the second material produces a gas and relaxing to form a visible bubble image. The two vesicular materials may be p-dimethylamino benzene diazonium zinc chloride salt and 7- dimethylamine-3-oxo-dihydrobenzo-1, 4-thiazine- 6 diazanium chloride salt which are respectively ultra-violet and visible light-sensitive, a heatsensitive material such as N, N'-diethyl-N, N'- dinitrose-torephthalimide and a photosensitive material and two heat-sensitive materials which decompose at different temperatures. The relaxation step is performed by heating.

Title: Magnetic recording and reproducing arrangements
IPC: G11B25/04
Filed: 1971-10-06
Abstract: 1369801 Magnetic sheet,recorder RICOH KK 6 Oct 1971 [5 Nov 1970] 46432/71 Heading G5R A magnetic recorder of the type in which a record sheet of magnetizable material (not shown) is positioned on projections 4, Fig. 1, and a magnetic record/playback head 8 is pressed against the record sheet and then driven in a spiral path over the sheet, is characterized in that means are provided for automatically retracting the head 8 from the record sheet when the recorder is operated in a non-record or non- playback mode, e.g., fast rewind. As described the head 8, Figs. 2, 4, is mounted on a plate 35, spring 37 urged upwards from a table 31 towards the record sheet. The table 31 in turn, is mounted on two rods 29a, 29b for radial movement on a disc 17. In the recording or playback mode, the disc 17 is rotated in the direction of arrow A, causing via gears 21, 23, a lead screw 24 to move the head mounting table 31-and hence the head 8 also-radially towards the centre of the disc so that the head 8 describes a spiral path relative to the record sheet. If the disc 17 is rotated in the opposite direction, a lever 59, Fig. 6, having extension 59a, 59c (see also Fig. 2) and being pivoted on an unthreaded portion of the lead screw 24 by a friction clutch arrangement 62, 63, is rotated by the lead screw to rock a lever 57 causing the end 57a to move the head mounting plate 35 downwards away from the record disc. (When the lead screw rotates in the opposite direction the extension 59c prevents the lever 59 moving). Modifications of this arrangement are described (Figs. 8, 9, not shown) and an arrangement is also described in which a flexible strip 74, Fig. 12, is drawn between the head 8 and the record 3 when the head is moved in the reverse direction. In a further arrangement the head is retracted in dependence upon the speed of rotation of the disc 17 rather than its direction of rotation. In this arrangement, if the disc 17 is rotated sufficiently fast, a weight 76a, Fig. 10, on the end of a lever 76 is flung outwards. causing its end 76b to pivot the lever 57 as in Fig. 6. The basic drive mechanism for moving the head towards the centre of the disc 17 incorporates an arrangement for retracting the head from the record when the head reaches its innermost position and for moving the head rapidly, during one rotation of the disc, back to its datum position at the edge of the disc 17. This arrangement includes a plate 42, Figs. 2, 4, normally spring 44 urged downwards, which is moved upwards by a cam 49 when the head assembly reaches its innermost position, so as to rock a lever 38 and thereby retract the head from the record. At the same time a further lever 45, Fig. 5, is also rocked to disengage the table 31 drive from the lead screw 24, and a stud 51, Fig. 2, carried by the plate 42, engages with, and latches on to, a stationary cam 52 rigid with the shaft 21a, so that during the next complete rotation of the disc 17 the head assembly is returned to its datum position at the edge of the disc.
